1 Claim. (Cl. 240-81) My invention relates generally'to lamps and moreparticularly to an improved type of fixture which is used in connectionwith incandescent lamps.

One of the objects of my invention is to provide an article ofmanufacture of unitary construction which has an opaque body portionshaped to simulate a candle stem and a reflecting diffusing surfaceformed of the same material as the body portion, but permitting passageof incandescent lamp rays.

Another object is to provide an incandescent lamp ray reflector having atranslucent body to permit passage of incandescent lamp rays and adepending body portion shaped to simulate a candle stem and formed ofthe same material as said reflector but having an opaque surface toprevent vision of the structure contained therewithin.

Another object is to provide a candle simulating stem and diffusingshade all formed of the same material having a tubular body portioncolored to provide an opaque wall and a translucent shade to permitpassage of incandescent lamp rays.

Another object of my invention is to provide a unitary candle simulatingstem and reflector surface which is integrally moulded from a plasticcompound in which the stem portion is treated to have the qualities ofopaqueness, and the reflector surface to have the qualities oftranslucency.

In the drawing:

Figure 1 is a side elevation of the upper portion of a lamp showing myinvention applied thereto,

Figure 2 is a view partly in elevation and in cross-section showing myinvention applied to the bracket extension of the lamp,

Figure 3 is a perspective view of my invention.

From the drawing it will be seen that the lamp is provided with theusual hollow pedestal I0 and supporting bracket I I. The bracket isformed of two complemental sections and has a plurality of radiallyextending arms I2, each of which arms has an extension I3, provided witha flange I4, which is adapted to receive the tubular or sleeve portionof my invention, presently to be described. Secured to the lower bracketsection I5, as by threaded bolt i6, is an upright support I'I whichcarries the usual socket Ila in which is threaded the incandescent lampI8. Mounted on the bracket i I, is a standard 2D which suitably supportsthe usual lamp shade 2|. Current supply wires or conductors I9,connecting at one end with terminals of the socket I'Ia extend throughthe arms I3 and into the hollow pedestal I0, for connection with asuitable plug which communicates with the electric current supply. Asuitable switch on the lamp, not shown, controls the current supply tothe lamps I 8.

The candle simulating stem and diffusing reflector or shade comprise anopaque body or sleeve -portion 22 of sumcient length, shape andappearance to resemble the usual candle stem. Integrally formed ormoulded with the sleeve portion .or securely fastened thereto is atranslucent bowl shaped reflector or shade 23, which extends upwardlysufficiently to surround the filament of the lamp. On the body portionadjacent the shade I provide an annular bead 24, which engages with theoutside wall of the socket I'Ia for positioning the stem and preventingtransverse relative movement thereof.

As will be seen from Figure l of the drawing, the shade or diifusingbowl surrounds the lower portion of the incandescent lamp, therebyobstructing from View that portion of the incandescent lamp that wouldotherwise be visible, when viewed from a position under the lamp. Theshade will direct and reiiect some of the light rays upwardly to bediffused by the ceiling, while other rays will lter or pass through thetranslucent shade. Since the large main shade 2| will surround the upperexposed portions of the incandescent lamps, no part of such areclirectly visible and consequently all glaring effects are obviated.

In the manufacture of my invention I prefer to mould my structure byusing a plastic compound rnade of a powder or granular mixtureconsisting generally of a synthetic resin as a binder and a fibrousmaterial as a filler in combination with other ingredients. Such mouldedstructures are light in weight, durable in structure and possess thequality of unbreakability to a great extent and are well known to theplastic trade under various trade names such as Beetleware, Plaskon,Textolite, and Unyte. Other similar plastic compounds can be used withequally good results. Various pigments to produce different colors oropaqueness can be used with the plastic compound.

It will be understood that though I have suggested the construction ofmy invention from plastic compounds, having the above characteristics Ido not desire that my invention be limited thereto, as other materialsmay be used.

Manifestly, the construction shown is capable of considerablemodification and such modioation as is within the scope of my claim, Iconsider within the spirit of invention.

What I claim is:

In a lamp structure including a bracket and an upstanding supportsecured thereto and supporting an incandescent lampi, an opaqueelongated body portion surrounding said upstanding support, asemi-spherical shaped bowl having a translucent surface and formedintegrally with said body portion and extending therefrom to surroundthe filament portion of said incandescent lamp, an annular beadpositioned intermediate the support and bowl and adapted to secure saidbody against relative movement with respect to said support.

THEODORE CHANOCK.
